As predicted, pairwise Dest for the racing homer to feral comparison was among the lowest 0.1% of all pairwise comparisons (Dest = 0.006), and pairwise FST was the lowest for any pairwise comparison (FST =0.049). Therefore, feral pigeons and racing homers show very little genetic differentiation, and wayward racing homers probably make a substantial contribution to the genetic profile of this local feral population.
